Did you even read any posts above yours?Well now that "backup loaders are a thing", how close are we from USB 3.0 harddrive/flash drive/SSD loading in docked mode?
"Backup loaders are not a thing" as backups (XCI files) are not loadable through ReiNX/RejNX/Atmo and there's no homebrew that loads backups.
Only TX has one built into their SX OS which in fact isn't a backup loader as well as it only redirects the launch of an inserted cartridge to launch it from a XCI from the SD instead.
However we can install NSP files and run them inside our custom firmwares thanks to sig patches if that's what you meant.
But as @AdamFX990 wrote, this will take some time until it's possible from (and to) USB.
